drm/amd/display: Enabling PSR support for multiple panels
[why]
Updating PSR interfaces to allow PSR enablement
per eDP panel.
[how]
- Copying PSR command structures to DC
- Changing function interfaces to pass panel instance
- Communicating with DMUB per link instead of assuming
to use a single one
-Iterating through all PSR capable panels when enabling/disabling
all
